Identification of Starch in Milk Protein Gels Using Confocal Microscopy
Various starches are common in dairy products. Historically, the standard staining technique for starch has been Lugol's Iodine. This dye, a general stain for starch is not fluorescent and only limited information can be obtained using transmission light. Fluorophores do not attach to starches. We have developed a method in which starches are derivatized so that fluorophores attach.
